The COSMO-CLM needs initial and boundary data provided by a model covering a larger area than the simulation area of your chosen COSMO-CLM domain. Possible data can be taken eg. from
- Reanalysis
- GCM
- RCM
- COSMO-CLM (in case of double nesting)
A number of meteorological variables are needed as initial and boundary data.
These data are the input for the interpolation programm INT2LM which transfers the data onto the COSMO-CLM grid. However, these data can not be used right away (except the output of a coarser COSMO-CLM simulation), because they are in different output formats and have to be converted to a standard that INT2LM can read (so called "INT2LM ready" data).
